 Figure 4.-Monthly water demand by eating and drinking establish-
 ments of different sizes and time open per week (DH=size
 of dining area times hours open per week), for average bar
 size and hours open, as affected by price, Dade and Mon-
 roe Counties, 1975-1976 (data from Appendix B, Table 4).


 Summary of Individual Store Demand Estimation

 Price was found to be an important variable in the demand
 for water by individual types of establishments. Water pur-
 chases were also shown to increase as the size of establishment
 increased. The implications of these findings can be examined
 in light of aggregate data for the area. The aggregate demand
 for water in the Miami Standard Metropolitan Statistical Area
 (SMSA), which is coincident with Dade County, is examined
 in the next section.


 AGGREGATE WATER DEMAND

 There are a large number of different types of commercial
establishments in the study area. In this respect, the area is
similar to any other large metropolitan area. The Miami SMSA
is somewhat atypical, however, as a large portion of the com-
mercial water use is related to the tourist trade.
